Now that's impressive

I can't run more than a mile without feeling pretty tired and being out of breath. I know a few people who run marathons, and that is extremely impressive. But this guy is absolutely insane. Read this article in the NY Times about Dean Karnazes, Ultramarathon extraordinaire. Here's a quote from the article about some of his running accomplishments...

"He has run 75 hours straight, 262 miles down the coast of California. He regularly runs all night, 70 miles or more, and in fact dictated much of his book into a tape recorder that he carried while he ran. He has completed many of the nation's toughest 100-mile trail races in under 24 hours. He once ran a marathon at the South Pole, in running shoes."

Wow.
